Optical Isolation with Microring Modulators
Nathan Dostart, Hayk Gevorgyan, Deniz Onural +1
Optical isolators, while commonplace in bulk- and fiber-optic systems, remain a key missing component in integrated photonic systems. Isolation using magneto-optic effects has been…
Multiplexing Guided Optical and Acoustic Waves for Efficient Acousto-Optic Devices
Nathan Dostart, Miloš Popović
Acousto-optic devices utilize the overlap of acoustic and optical fields to facilitate photon-phonon interactions. For tightly confined optical and acoustic fields, such as the sub…
Serpentine optical phased arrays for scalable integrated photonic LIDAR beam steering
Nathan Dostart, Bohan Zhang, Anatol Khilo +6
Optical phased arrays (OPAs) implemented in integrated photonic circuits could enable a variety of 3D sensing, imaging, illumination, and ranging applications, and their convergenc…
Integrated optical isolators using electrically driven acoustic waves
Nathan Dostart, Yossef Ehrlichman, Cale Gentry +1
We propose and investigate the performance of integrated photonic isolators based on non-reciprocal mode conversion facilitated by unidirectional, traveling acoustic waves. A tripl…
Elastic Wave Eigenmode Solver for Acoustic Waveguides
Nathan Dostart, Yangyang Liu, Miloš A. Popović
A numerical solver for the elastic wave eigenmodes in acoustic waveguides of inhomogeneous cross-section is presented. Operating under the assumptions of linear, isotropic material…
